  The SAP error message DMC_RT_MSG073, which states "Computer &1: number of processes is <= 0," typically indicates an issue with the configuration of the SAP system, particularly in relation to the number of processes that are allowed to run on a specific computer or server.
  Cause:
  
  Configuration Issue: The error usually arises when the number of processes configured for a particular application server or instance is set to zero or a negative value. This can happen due to incorrect settings in the instance profile or during system configuration.
  Resource Limitations: The server may not have enough resources (CPU, memory) to support the number of processes that are configured.
  System Parameters: Certain system parameters related to process management may not be set correctly, leading to this error.
  
  Solution:
  
  
  Check Instance Profile:
  
  Go to the SAP system and check the instance profile settings. You can do this using transaction code RZ10.
  Look for parameters like rdisp/wp_no_dia (for dialog work processes) and rdisp/wp_no_btc (for background work processes). Ensure that these values are set to a positive integer.
  
  
  
  Adjust Parameters:
  
  If the values are set to zero or negative, change them to appropriate positive values based on your system's capacity and requirements.
  After making changes, save the profile and restart the instance for the changes to take effect.
  
  
  
  Check System Resources:
  
  Ensure that the server has adequate resources (CPU, memory) to handle the number of processes you are trying to configure.
  Monitor system performance and adjust the number of processes accordingly.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SM21) and developer traces (transaction ST22) for any additional errors or warnings that might provide more context about the issue.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to process management and configuration for your specific version of SAP.
